Oleum train tanker vehicle unloading
Technical field
The utility model relates to unloading of in Chemical Manufacture fuming sulfuric acid, relates in particular to the oleum train tanker vehicle unloading of aluminum fluoride in producing.
Background technology
The method that present fuming sulfuric acid unloads acid is a lot, has centrifugal pump to unload acid system, and pressurized air is unloaded acid system, and acid system is unloaded in siphon.Use centrifugal pump to unload acid, then high-order acid tank must be set, before unloading the acid operation, the acid in the elevated tank is poured in the centrifugal pump.If like this operation control improper, the danger of the acid that can occur overflowing.Use pressurized air to unload acid because dangerous height seldom is used at present.Use siphon to unload acid system and unload acid, flow is limited in the siphon, can not reach the requirement of unloading acid fast.
The utility model content
Provide a kind of oleum train tanker vehicle unloading in order to solve the problems of the technologies described above the utility model, purpose is to realize fuming sulfuric acid automatic airtight car unloading operation, satisfies safety, quick-release, requirement that bed material is few simultaneously to greatest extent.
For reaching above-mentioned purpose, the utility model is achieved in that a kind of oleum train tanker vehicle unloading, wherein train tanker vehicle is communicated with by unloading sour oil filling riser and the integral type pump groove group of unloading, the integral type pump groove group of unloading is communicated with the water tourie by pipeline, and the water tourie is communicated with vacuum pump by the vacuum pump extraction pipe.
Described integral type unload pump groove group comprise expansion tank and with expansion tank by pipeline bonded assembly submerged pump.
Described submerged pump is 1-4, and submerged pump is communicated with the nadir of expansion tank.
The induction pipe of described submerged pump is communicated with expansion tank.
Described submerged pump outlet pipe communicates with carrying the acid tube road.
Be provided with valve between described submerged pump outlet pipe and the conveying acid tube road.
Described expansion tank is a vertical storage tank, and expansion tank is provided with tubular type liquidometer and vacuum conditions pipe.
Described water tourie is provided with the fluid-tight arm.
Described water tourie bottom is provided with the PH index gauge.
Described water tourie is provided with coolant inlet pipe and gargle pipe.
Described coolant inlet pipe is located at the top of water tourie.
Described gargle pipe is located at the bottom of water tourie.
Described vacuum pump is a water-ring vacuum pump.
Described vacuum pump is discharged gas by the vacuum pump freeing pipe.
Described vacuum pump extraction pipe is provided with the vacuum pump valve.
Advantage of the present utility model and effect are as follows: fuming sulfuric acid unloading unit safety of operation, reliable, easy.Submerged pump is installed on the nadir of expansion tank, can actv. be discharged by spent acid in the expansion tank.Acid solution in the expansion tank can not only be put only, the accident of stopping takes place; And can effectively reduce the acid solution leakage, the water tourie can prevent that effectively acid mist enters vacuum pump in the fuming acid, avoids the corrosion of vacuum pump.
